Figure 2. Exon/intron structures of cry genes.
(A) Exon/intron structures of zebrafish and coelacanths cry1a genes, chicken Cry1 gene and human CRY1 gene. (B) Exon/intron structures of zebrafish and coelacanth cry2 genes, chicken Cry2 gene and human CRY2 gene. (C) Exon/intron structures of zebrafish, coelacanth, frog, anole, zebra finch and chicken Cry3 genes. The sequences at the splice sites crossing or flanking exons are shown on top of each exon boundary. Dr, Danio rerio; Lc, Latimeria chalumnae; Hs, Homo sapiens; Gg, Gallus gallus; Tg, Taeniopygia guttata; Ac, Amoles carolinensis and Xt, Xenopus tropicalis. Exon sizes are not drawn to scale. Dark grey columns indicate highly similar exons of the same size among different species and light grey columns similar exons among different species.
